I'm not further along I can tell you that much, there's also a pretty decent sized, vocal older population on this site, herbs can have similar effects to HRT, but it's safer to have a doctor's supervision in this, because the side effects of things can be life threatening if not monitored.
That much said, tender nips is a very common early side effect, I'm not on anything yet, but I plan to cover up with something. Maybe something like pasties for when I'm concerned a bra might show in male mode, but the best solution to that problem is a bra of a comforting material.
